摘　　要：为考察电催化氧化处理煤化工二级出水的性能,采用阳极氧化法制备了网状Ti/TNTs/SnO 2电催化电极,以煤化工二级出水为研究对象,研究不同因素对COD和TOC去除率的影响。结果表明:该电极表面形貌致密无裂痕,其电极加速寿命可达107.6 h;采用此电极处理未达标的煤化工二级出水时,当电极之间的距离设定为10 mm且电流密度维持在10 mA/cm^(2),反应4 h后,COD和TOC去除率可达到81.8%和64.2%,出水达到工业用水标准,符合企业回用排放水质ρCOD≤30 mg/L的要求。This paper is intended to investigate the performance of coal chemical secondary effluent treated by electrocatalytic oxidation.The study includes preparing a mesh Ti/TNTs/SnO 2 electrocatalytic electrode by the anodic oxidation method,and studying the effects of different factors on the removal rates of COD and TOC by taking coal chemical secondary effluent as the research object.The results indicate that the surface morphology of the electrode is dense without crack,and its electrode acceleration life can reach 107.6 hours.By using this electrode to treat substandard coal chemical secondary effluent,when the distance between the electrodes is set to 10 mm with the current density maintained at 10 mA/cm^(2),after 4 hours of reaction,the COD and TOC removal rates can reach 81.8%and 64.2%,respectively,and thus,the effluent meets the industrial water standard and the reused water quality requirements byρCOD≤30 mg/L.
